Common name: cauliflower.
Latin name: Brassica oleracea var. botrytis.
Family: Cruciferae (Brassicaceae) [Brassicaceae Images].
Biennial, mostly grown as an annual.
Direct seeded or transplanted.
Harvested organ: mostly white [but in some varieties, purple], enlarged flower-head, called a curd.
Cool season, cold hardy.
Temperature optimum: 10 and 20 C.
Soil pH optimum: 6.0 to 6.5.
Hand harvested (typically when heads 15 - 25 cm in diameter).
Heads may become discolored and develop an undesirable flavor when exposed to sunlight.
Longest leaves are loosely tied together over the head to "blanch" the head for 5 to 10 days before harvesting.
Heads cut with 1 or 2 whorl leaves to protect the head.
